I've settled on FOMABROM VC VELVET VARIANT IV123 for now. It is as warm as I have seen, and develops fully in LPD 1:3 in 2 to 2-1/2 minutes with rich full blacks, smooth mid-tones and highlights. The paper base is white, not off white or yellow or cream, etc. It is not as heavy a paper as the Ilfords and I find it needs about 15 more CC's of Magenta filter at each grade than they suggest.
